Sometimes people see in us what we cannot. Get that confidence from your mrs and friend and use that.
I am not in favor of getting a strongly stressful job in any age and would not be advocating to try getting it.
I am open to trying new things in any age though. My honest suggestion, apply, if they call for the interview, do it. Whatever, the result, you don't want to join, don't. But, this would be interesting, a change in the routine. I am sure, you'll enjoy it for a long time to come. Just keep in mind that your are doing it for fun and nothing else. Don't be careless in showing it in front of them, but do not care what they think. They would have nothing on you. This would be just an interesting experiment.
I haven't sleep for last 42 hours so I appologize if my words and suggestions are not organized or are stupid... I think, soul of the message is conveyed though. We take and take and take stress in all our lives, just do it once without taking the stress.
I loved the photos.
